Introduction to LIGO & Gravitational Waves

INTRODUCTION

 

Throughout history, humans have mainly relied on different forms of light to observe the universe. Today, we are on the edge of a new frontier in astronomy: gravitational wave astronomy. Gravitational waves carry information on the motions of objects in the universe.  
Since the universe was transparent to gravity moments after the Big Bang and long before light,
gravitational waves will allow us to observe further back into the history of the universe than ever before. And since gravitational waves are not absorbed or reflected by the matter in the rest of the universe, we will be able to see them in the form in which they were created. Moreover, we will effectively be able to “see through” objects between Earth and the gravitational wave source.
